World’s First Bionic Eye Implant In Melbourne

Bionic researchers have successfully performed the first bionic eye implant of an early at the Royal Victorian Eye and Ear Hospital in .

The bionic eye was implanted in a woman who has profound vision loss due to retinitis pigmentosa, an inherited condition.

Ms Dianne received the ‘pre-bionic eye’ implant which was switched on last month at the after years of hard work and planning.

The project is one of many exciting medical developments to come out of the Parkville Precinct, which encompasses the University of Melbourne and a world class research facilities cluster.

With researchers watching via video link in the next room, Ms Ashworth reported experiencing some vision: “I didn’t know what to expect, but all of a sudden, I could see a little flash…it was amazing. Every time there was stimulation there was a different shape that appeared in front of my eye,” she said.

The prototype consists of a retinal implant with 24 electrodes. A small lead wire extends from the back of the eye to a connector behind the ear. An external system is connected to this unit in the laboratory, allowing researchers to stimulate the implant in a controlled manner in order to study the flashes of light.

Feedback from Ms Ashworth will allow researchers to develop a vision processor so that images can be built using flashes of light. This early prototype does not incorporate an external camera – yet. This is planned for the next stage of development and testing.

Director of , Professor Anthony Burkitt, said: “This outcome is a strong example of what a multi-disciplinary research team can achieve. Funding from the Australian Government was critical in reaching this important milestone.”

Sally Capp, Agent General for Victoria in the UK said: “The bionic eye implant is a stunning example of the many innovative medical developments that are being produced by the Parkville Precinct and the wider Victoria medical research community.

The collaborative effort from the universities, research institutes and National Information and Communications Technology Australia (NICTA), is testament to Victoria’s dedication to discovering life-changing medical solutions for people all over the world. The success of the bionic eye implant is a sign of things to come.”

Director of the Bionics Institute, Professor Rob Shepherd, led the team in designing, building and testing this early prototype to ensure its safety and efficacy for human implantation. Cochlear technology supported aspects of the project.

“We are working with Ms Ashworth to determine exactly what she sees each time the retina is stimulated using a purpose built laboratory at the Bionics Institute. The team is looking for consistency of shapes, brightness, size and location of flashes to determine how the brain interprets this information. Having this unique information will allow us to maximise our technology as it evolves through 2013 and 2014,” he said.

Bionic Vision Australia is one of only two projects funded nationally to develop technology to restore a sense of vision to people with profound blindness. Both syndicates are Melbourne based. Bionic Vision Australia is a national consortium led by The University of Melbourne and involving two Victorian independent medical research institutes – the Bionics Institute and the Centre for Eye Research Australia – NICTA and UNSW. The Monash Vision Group is a consortium of Monash University, Alfred Health, MiniFab and Grey Innovation.
